Sunkist fruit snacks, blue pineapple?

My friend always eats these Sunkist fruit snacks, and she always finds one that appears to be a blue pineapple. The only weird thing is that there is no mention about a "blue pineapple" whatsoever on the small pouch, or the box itself. So, is this "blue pineapple" supposed to be included in the fruit snacks, and has anyone else seen this "blue pineapple" fruit snack?
